Following the release of the Electoral Boundaries Review committee report for the 2020 general elections, Punggol East SMC was merged into Sengkang GRC.

[1] Punggol East SMC was the sole constituency to feature a three-cornered contest for the 2011 election.

The election was won by People's Action Party's Michael Palmer, who was the incumbent MP of the ward with 54.54% of the votes, beating Workers' Party's newcomer Lee Li Lian and Singapore Democratic Alliance's secretary-general Desmond Lim, who garnered 41.01% and 4.45% of the votes, respectively in the 2011 general election.

After the election, the area division was renamed "Rivervale" by WP and "Sengkang East" by PAP.
